Magnesium Fastener Manufacturing Method and A Magnesium Fastener Member Produced Thereby

Abstract

A magnesium fastener manufacturing method includes the steps of: using a magnesium or a magnesium alloy to form a magnesium wire or a magnesium rod; processing cold forging, warm forging or hot forging the magnesium wire or the magnesium rod to form a magnesium fastener member. When processing warm or hot forging, a directly heating treatment, a thermal isolating and directly heating treatment, or a directly heating and thermal isolating treatment is selectively applied to heat the magnesium wire or a magnesium rod to a predetermined temperature.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention The present invention relates to a magnesium fastener manufacturing method and a magnesium fastener member produced thereby. More particularly, the present invention relates to a magnesium fastener manufacturing method for cold, warm or hot forging a magnesium wire or rod to produce a magnesium fastener member.[0002]2. Description of the Related Art[0003]U.S. Pat. No. 6,328,657, entitled “Threaded fastener and a method of making the same,” discloses a threaded fastener or the likes directly made by a moderate temperature-forging process and from a raw magnesium material. The raw material may be selected from pure magnesium provided with industrial grade or any magnesium alloy. Before forging operation, the raw magnesium material has a degree of a superplastic property, and a fine-granulated metallographic internal texture.[0004]In the above manufacturing method, a predetermined shape of the threaded fastener is directly forg...

AI Technical Summary

Benefits of technology

[0007]The primary objective of this invention is to provide a magnesium fastener manufacturing method and a magnesium fastener member produced thereby. A preformed magnesium wire or rod with a predetermined diameter is formed from a raw magnesium or magnesium alloy material, and the wire or rod is forged to produce a forged piece of the magnesium fastener member. Accordingly, the magnesium fastener manufacturing method is successful in simplifying the entire process.

Problems solved by technology

However, the above manufacturing method is lack of consideration to directly forge the original shapes of the raw magnesium material suitable for forming the predetermined shape of the threaded fastener.

It will be known in the art that the directly forging method for the raw magnesium material is rarely successful and cannot simplify the entire process.
